Title: Milking machines
IPC: A01J5/007
Filed: 1973-05-21
Abstract: 1434392 Milking machines ALFA LAVAL AB 25 June 1974 [21 May 1973] 24118/73 Heading A1M The application of vacuum to the pulse space between a teat cup and liner is controlled in response to the milk flow rate to avoid back pressure in the milk pipe. A flow monitor 4 comprising a float 12 which actuates a reed switch 13 causing a relay 9 to de-energise solenoidal valves 7 which restrict air passage from the pulse space when milk flow is slow. The valves are biased by springs B towards the closed postion and have a bleed channel A in the valve seat to allow gradual evacuation of the pulse space whilst milk flow is slow. When the flow exceeds a predetermined level the monitor operates the reed switch causing the relay 9 to energise the solenoids 6 opening the valves for normal pulse space evacuation. The valves may be operated pneumatically or hydraulically.  A deflector may be inserted in the line below the teat.
Patent GB-737353-A (GB)
Title: Improvements in the braking of motor vehicles with four-stroke reciprocating internal combustion engines
IPC: F01L13/06
Filed: 1953-09-01
Abstract: 737,353. Regulating; valve gear. SOC. ANON. A. SAURER. Sept. 1, 1953 [Sept. 24, 1952], No.24126/53. Class 7(6). In a four-stroke engine having means for cutting off the fuel and throttling the exhaust pipe to produce engine braking, the actuating means of the exhaust valve is adjusted to cause opening of the exhaust valve on the normal compression stroke as well as on the normal exhaust stroke simultaneously with the throttling of the exhaust pipe. In Fig. 1 an auxiliary valve lever 9 mounted on an eccentric pivot 8 and connected to the exhaust valve tappet 4 through a rod 14, is normally positioned out of contact with the cam 3 which acts directly on the tappet 4 to open the exhaust valve once each cycle for normal four stroke operation. For engine braking, a lever 10, connected to means for throttling the exhaust pipe and cutting off the fuel, is rotated to adjust the eccentric 8 to bring the lever 9 against the cam 3 whereby the exhaust valve is additionally opened through the lever 9 and rod 14 on the normal compression stroke, the braking action of the throttled exhaust gases thus occurring twice on each complete cycle. In a modification the lever 9 has a fixed fulcrum and is put into or out of operation by a movable link connected to the tappet 4. In Fig. 6 each exhaust valve has associated therewith two cams 65, 66 and tappets 62, 63 which operate the valve tappet 60 through a lever 72 pivoted on the tappet 62 and a movable roller 70. In the position shown the roller 70 is immediately above the tappet 62 whereby the tappet 63 is rendered ineffective and the engine operates normally. For engine braking the roller is moved to an intermediate position (shown dotted) whereby each tappet is operative and the exhaust valve is opened on each inward stroke of the piston, the exhaust pipe being simultaneously throttled. Alternatively for braking the roller 70 may be moved to a position above the tappet 63 which renders tappet 62 inoperative the cam 66 in this case having two cam rises 180 degrees apart to open the exhaust valve twice in each cycle. In Fig. 3 the exhaust valve is normally operated by a central cam 42 flanked by two cams 44, which latter are brought into operation for engine braking to open the valve on the normal compression stroke by the introduction of a forked member 56 between the cams and the tappet 48. In a further modification the cam shaft actuating the exhaust valves may be moved axially for engine braking to bring double lobed cams into action to cause the desired exhaust valve opening. The admission valves may also be caused to open twice each complete cycle during engine braking in addition to the exhaust valves by mechanism similar to that used for the exhaust valves, the time of opening on each outward stroke preferably being arranged when the air pressure in the cylinder is equal to that in the intake pipe.

Abstract: 750,245. Brake control systems. ENGLISH ELECTRIC CO., Ltd. Aug. 27, 1954 [Sept. 1, 1953], No. 24142/53. Class 103 (1). [Also in Group XXIV] An actuating mechanism for a control device such as the valve 22 controlling the application of the brakes of a mine winder comprises a manual actuating lever 10, an automatic control device 20, and a change-over lever 23 for positioning the mechanism for manual or automatic control. The manual lever 10 is connected by a linkage 11, 12, 13, 15 and the automatic device 20 by a link 19 to the ends of a lever 16 coupled at its centre by a link 21 to the brake valve 22. The lever 13 is pivoted to the end of a lever 14 controlled by the change-over lever 23 through lever 24 and link 25. For manual operation the mechanism is set as shown in full lines, the lever 23 closing a switch 27 which actuates a solenoid of the device 20 to raise the left-hand end of lever 16 and hold it in fixed position. The lever 10 can thus be operated freely to move the brake valve 22 between full " on " and " off " positions. To change to automatic control the lever 10 is first moved to the " on " position and the lever 23 moved from manual to the automatic position where it is locked. The link 15 is thereby raised against an abutment 28 to lock the lever 10 against movement and to raise the right-hand end of lever 16. The left-hand end of lever 16 is however lowered by the opening of switch 27 by the lever 23 so that the brake valve 22 remains in its lower " on position. The mechanism is now ready for automatic operation through the device 20 by control circuits brought in by another switch (not shown) actuated by the lever 23. In a modified arrangement the manual and change-over levers are combined and a sideways movement of the manual operation lever is utilized to operate, through a bell crank lever and a link, the member 24 of the linkage previously described and the switch 27. The electric solenoid device 20 for automatic control may be replaced by an electro-hydraulic or electro-mechanical thruster.

Title: Improvements in or relating to rotary digesters for the production of paper pulps
IPC: D21C7/02
Filed: 1957-07-31
Abstract: <PICT:0832646/IV (a)/1> A rotary digester for the production of paper pulp from woods or vegetable matter is in the form of a cylinder having hemispherical or domed ends and is rotatable about an axis at right angles to the longitudinal axis of the cylinder, and the liquor with which the wood or vegetable matter is to be digested is heated in a heat exchanger outside the digester and is fed into the digester through a conduit rotating with it which leads to sprinkling or liquor discharge means located at or near the ends of the digester. As shown, the digester comprises a casing 1 rotatable around an axis XY and provided at its ends with apertures 2, 3 for charging and discharging the digester.  Treating liquor enters the digester through a conduit 10 which extends through one of the two hollow half-shafts of rotation of the apparatus, and the liquor then passes through two conduits 6, 8, a coil of perforated pipe 7 and a circular perforated rose 9.  The liquor flows through the mass of vegetable matter in the digester, as indicated by the arrows, through an enclosure 4 consisting of a perforated sheet steel member covered with steel gauze, and into a liquor discharge conduit which extends through the other half-shaft of rotation.  Liquor is withdrawn from the digester by the stationary centrifugal pump 12 and pumped through the heat exchanger 13 and conduit 14 back to the digester inlet conduit 10. In a modification the conduit 10 consists of two concentric pipes, one of which communicates with the conduit 6 and the other with the conduit 8.  The two concentric pipes communicate with the inlet and discharge of a second centrifugal pump in such a manner that liquor may be circulated via conduits 6 and 8 through the digester without passing through the heat exchanger.  The second pump may also be used for charging the digester with liquor and for withdrawing liquor therefrom.
